Patent DE-3241681-A1 (DE)
Title: Process and apparatus for treating liquids, in particular for desalting aqueous solutions
Inventor: KUNZ GERHARD DIPL CHEM DR ING
IPC: B01J49/30
Filed: 1982-11-11
Abstract: In the process, the liquid is exposed in sequence to different absorption processes, the treatment process of the liquid being carried out at an elevated reaction temperature and the electrical energy converted into heat energy being utilised in such a manner that heat directly produced in the desalting process is kept in the desalting chambers by means of insulation against loss by conduction and radiation and the capacitative heat of the liquid streams leaving the desalting process is supplied again to the liquid streams flowing into the desalting process. <IMAGE>

Title: Chuck for tool inserts, in particular screwdriver bits
Inventor: LIESER KARL
IPC: B25B23/00
Filed: 1982-11-24
Abstract: The invention relates to a chuck for shank ends, of non-round design, of tool inserts, in particular screwdriver bits, having a bush, which corresponds in its cavity to the non-round cross-section, and a ball which acts on the shank and is assigned a sleeve which is displaceable against spring action and has a clamping face, and proposes, for improved handling of the structural shape, that the sleeve (9), capable of displacement in the insertion direction of the shank (4) for transition to the release position, receives the ball (13) in a projecting wing (10), and the clamping face (15) sits on the inner flank of an end ring (14) enclosing the edge of the bush (1) and the wing (10). <IMAGE>

Patent DE-3329391-A1 (DE)
Title: Wiper blade for motor vehicle windows
Inventor: WOLLENSCHLAEGER DIETER
IPC: B60S1/38
Filed: 1983-08-13
Abstract: A wiper blade is proposed which serves for cleaning motor vehicle windows. The wiper blade comprises an elongate wiper strip which is pressed onto the window to be wiped and is held by a multi-component carrying bar frame. A wiper arm which is spring-loaded against the window engages on a superordinate main bar of the carrying bar frame. At least one sub-bar which passes on the spring force and is located at least partially between the main bar and window is coupled to the main bar. A component which has a surface which is acted on during operation of the wiper blade by the air stream originating from the slip stream is attached to the sub-bar. So that the contact pressure directed on the window is made as uniform as possible when the motor vehicle is moving, the attachment point of the component on the sub-bar is located between the connecting point of the wiper arm on the main bar and the joint between the main bar and sub-bar.

Patent DE-3337252-A1 (DE)
Title: Metal-encapsulated switch panel
Inventor: DIETZ WOLFGANG DIPL ING
IPC: H02B11/24
Filed: 1983-10-13
Abstract: For a metal-encapsulated switch panel of a medium-voltage or low-voltage switching and distribution installation, which switch panel is intended to be fitted with at least one protective wall, especially for maintenance or inspection purposes, which can be fitted into the interior of the switch panel between functional elements which carry voltage and those which do not, and with guide elements (15) which are arranged on the sides of the switch panel for holding and guiding this protective wall, it is proposed that the protective wall be constructed as a wall element (16) which can be rolled up in its insertion direction and whose insertion path can be matched to curves having small radii of curvature. This protective wall may have a cross-sectional path which undulates approximately sinusoidally in the insertion direction or in an approximately zig-zag shape, or a cross-sectional path which changes continuously at right angles (in a meandering shape). The cross-sectional path of the protective wall may, however, also have constrictions at approximately regular intervals, which constrictions in each case form wall regions which can be bent out easily and are like film hinges, similar to a louvre, and are composed of a number of rod-like elements which are placed at right angles to the insertion direction.   <IMAGE>
Patent DE-3338607-A1 (DE)
Title: Branching fitting for engaging into the interior of a pipeline
Inventor: NOOY BURTON VER
IPC: F16L55/105
Filed: 1983-10-24
Abstract: The invention relates to a fitting for engaging into the interior of a pipeline. In this case, the pipeline is secured such that neither fluid nor gas can flow out and such that it is unnecessary to pump the pipeline out or to cut off the pressure completely. In the first operation, a hole is cut in the pipe wall by means of a device which is incorporated in the fitting, and a plug is installed in the pipeline in the second operation. These two operations can be carried out without the fitting having to be removed from the pipeline. However, other operations can also be carried out using the fitting, for example cleaning deposits out of a pipe by the insertion of a part which is provided with brushes.

Filed: 1983-11-22
Abstract: The invention relates to a method and an apparatus for producing a tobacco rod, which consists of a core (K) and an annular layer (L1, L2), surrounding the latter, which differs in its material from that of the core. To this end, in a first duct section (4a), a corner of a tobacco duct (4) is first filled with tobacco and then the opposite corner is filled, so that a first tobacco layer (L1) is formed with a concave surface. A narrow rod of core material (K) is then applied in the centre of the first tobacco layer (L1), and is thereupon covered with a second tobacco layer (L2) of the same material as the first tobacco layer (L1). <IMAGE>

Abstract: A shower device (1) has in the customary manner a shower tray (2) with a drain (3), furthermore a shower cubicle and at least one regulating valve (5) with which the user can regulate the strength and intensity of the inflowing water. Furthermore, there are shower water outlets in the form of shower pipes (6) with which showering, above all after sauna treatment, is possible in such a way that the effect of the water is approximated as closely as possible to that of an immersion basin but without requiring an immersion basin. The shower device (1) has a supply container (8) with a limited quantity of water and a pump (9) and the drain (3) of the shower tray (2) opens out into the supply container (8) so that this water can be circulated again and again for as long as required and can be splashed or sprayed on the user again and again. He can therefore shower as long as desired, in which case he is only being showered with water that he has used himself without resulting in a high water consumption. After showering, the used water can be drained away and the supply container (8) can be filled with fresh water for the next user. <IMAGE>
